Because of how widely diplomatically enmeshed Terran was, its implosion has caused ripples that have set all of Dwilight ablaze.
Just as a side note: From my perspective, at least, I think that's a bit Terran-centric.
It looks to me more like large chunks of the continent were just looking for excuses to start their own little regional wars, and the various ripples that Terran's implosion
did cause have given them exactly what they wanted.
